读地震波波速与地球内部构造图,回答下列各题。

小题1:岩石圈是指

A.①的顶部

B.②的顶部

C.③的外部

D.①和②的顶部小题2:某地地下30千米处发生地震,这时地面上的人、附近不远处的飞鸟和池塘里的鱼,都会感到 

A.先上下颠簸,后左右摇摆

B.先左右摇摆,后上下颠簸

C.P波,上下颠簸

D.S波,左右摇摆

答案

小题1:D  

小题2:C

题目分析:

小题1:读地球内部构造图可知,①是地壳,②是地幔,③是地核。岩石圈范围包括上地幔顶部和地壳。所以指的是①和②的顶部,D对。A、B、C错。

小题2:根据地震波的有关知识,横波不能在液体中传播,所以在池塘里的鱼不会感到左右摇晃。纵波可以在固体、液体、气体中传播,所以都可以感到上下颠簸,C对。A、B、D错。

Technology is the application(应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via(通过) medical technology.

Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics(统计) show that the United States is continuing to pump billions of dollars annually(每年) into such efforts. So while we are running out of some scarce resources(少的资源) we may well find technological substitutes(代用品)for many of them through our research programs.

Therefore, in the final analysis the three major factors of production(land, labor and capital) are all influenced by technology. When we need new skills, on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.
